LOCK-VALVE.

Speccaton of Letters Patent.

Patented Sept.. la, i915.

ppplicat'on led October 9, 1912. Serial No. 724,702.

To all whom t may concern Be it known that I, JOHN F. BLYTHINc, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lock-Valves, of which the following is a description.

My invention belongs to that general class of devices known as lock valves, and relates particularly to a suitable valve and key controlled operating means therefor. The device is particularlyT designed for use on automobiles, motor boats, etc., for locking the valve controlling the supply of gasolene, but 'is not, however, confined to such use, as the same may be employed wherever found applicable.

rlhe invention has among its objects the production of a device of the kind described that is simple, efficient, convenient, and satisfactory, that will not easily get out of order,

and that cannot be operated by an unauthorized party tampering with the same.

To this end my invention consists of the novel construction, arrangement and combination of parts herein shown and described, and more claims.

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a sectional view of my improved device, and Fig. 2 is a sectional view taken substantially on line 2, 2 of Fig. 1.

Referring to the drawings, in which the preferred form of my device is shown, 1 and 2 represent the pipes for conducting the gasolene or other` iuid from a source of supply to the desired point. One pipe is connected to the inlet and the other to the voutlet of a suitable valve casing 3. Iheseparts may be connected iu any suitable manner:A

As shown, the caps 4f maintain the anges 6v on the pipes against displacement, packing 5 being provided if desired. rIhe casing outlet is controlled by a. valve member, preferably in the form' of a spherical ball 7, adapted vto' coperate when closed with a valve-seat 8 in the casing. When the device is locked the valve member 7 is maintained 'Ihe casing 1s` provided with an extended part M, having a recess therein, in which particularly pointed outin the upon its seat by amember 9, which is also arranged a spring 12, or its equivalent, which is adapted to normally raise the valve member 7 and maintain it in position in alinement with the outlet, or its valve. seatS. The valve is opened by depressing or pushing the valve member 7 into the recess in the part 14: against the pressure 0f the spring 12, and closed by permitting it to return to the position indicated in Fig'l. Y

F or operating the valve, I provide a longitudinal movable rod 15, which is preferably arranged within a casing 16, which may be secured to the vehicle part 18 when the device is used on an automobile by a bracket 17, and bolt or screw 19. The bracket 17 is secured to the casing 16 in such a way that it cannot be easily pulled or broken off. While the extended part 16 may be made integral with the casing 3, I preferably form the same separate and screw the same upon the extended part 20 of the casing, the extended part 16 being formed as at 21 to embrace the part 20.

- In order to prevent any leakage `of gasolene or other Huid about the rod '15, from the valve casing 3, packing 22 may be arranged as shown. To maint-ain the packing in po sition, parts 23 and 2a are arranged as shown. It is, of course, understood that any equivalent arrangement may be provided.

The size or length of the extended part 16 depends upon the preference of the'user, the same being suiiciently long so as to bring the locking device to a point where it may be conveniently reached. As shown, the casing or extended part 16 is provided with a guide 25 for the rod 15, and is enlarged slightly as at 26. Within'the enlarged part is arranged the locking mechanism, and in this connection it may be stated that I preferably use a Yale or similar lock, in which practically no two locks may be operated byv the same key.

rIlle locking mechanism is not-shown in detail, 30 being an outer casing, within which is arranged the locking cylinder 27, which is turned or operated by the key 28. Upon the rotatable cylinder 27, which is commonly known as the lock cylinder, I arrange a cam 29. This cam is so designed that when the cylinder 27 is turned with the key 2,8, the rod 15 is depressed, thereby depressing or moving the valve 7, and per- -27v is in position so that the cam does not bear upon the rod 15. When, however, it is desired to open the valve, the key is inserted and the cam turned, opening. the valve as described. When the valve member 7 is depressed, for example, as illustrated by the dotted lines in Fig. 1, the coperating member 9 is moved by the depressing of the valve member.A As soon as the valve, however, is raised by the spring 12, the spring 10 forces the member against the valve and maintains it upon its seat 8.

The device is particularly designed to pre vent the unauthorized use of automobiles, motor boats and the like, but it is applicable for other uses, as previously mentioned. When an automobile or boat is so equipped the owner or operator of the machine turns his key, thereby locking the valve so that the vehicle cannot be stolen or used, either when on the street, in thegarage, or in the case ofa boat when docked or anchored. It is impossible for anyone to operate the key or a pass -key 'and unlock'the device, re-

turning the key with the same unlocked, as

the key must be kept in the lock in order to keep the valve open. This is important where an automobile is in a garage and theV managenhas a pass key to several machines. In this case several machines cannot be unlocked by an employee in possession of a key authorized for use on another machine.

Having thus described my invention, it is obvious that various immaterial modifications may .be made in they same without departing from Ythe spirit of my invention,

hence I do not Wish to limit myself to the exact form, arrangement, construction, or combination of parts herein shown and described,` or uses mentioned.

What I claim as newand desire to secure by Letters Patent is:-

l. In a device of the kind described and in combination, a suitable valve casing provided with an inlet and outlet,a controlling valve in said outlet, means arranged in the inlet for maintaining said valve onits seat,

comprising a tubular sleeve slidably carried by the casing, a fixed tubular sleeve arranged in said inlet, and a spring memberv arranged to abut against both of said sleeves, and' normally force the slidable sleeve in the direction ofthe outlet of the casing, said casing provided with an ex. tended chambered part at one side, a longitudinally movable valve operating rod arranged in the chamber in said part and projecting into the valve casing, meansfarranged about said rod for preventing the escape4 of fluid from the casing into said chamber, key-controlled mechanism arranged at the end of said chambered part for operating said rod, including a lock casing secured in said part, and a rotatable barrel arranged therein and provided with a cam member on itsinner end arranged ec centrically the rod and only contacting with said rod at the end thereof.

2. In a device of the kind described and in combination, a suitable casing provided with an inlet and outlet, and with a valve seat at said outlet, said casing having a chambered extended part at one side and a recess therein at the opposite side, a spherical valve member arranged in said casing, means for normally maintaining said valve member in alinement with the valve seat, means for resiliently maintaining said valve on its seat, means for displacing the valve member and retainingthe same in said recess in position to the resilient means contained therein, comprising a longitudinal movable rod arranged in the chambered part and extending into the casing in contact with the valve member, a stuing box arranged about said rod'between said casing and extended part, a rotatable cam member positioned at the end of the rod and having a cam face in contactwith. the. rod end, and means for rotating, 'said cam, including locking means secured thereto. .a
